8d2474227f mpapic.c & mp_machdep: 
- removed TEST_ALTTIMER.
 - removed APIC_PIN0_TIMER.
 - removed TIMER_ALL.

mplock.s:
 - minor update of try_mplock for new algorithm where a CPU uses try_mplock
	instead of get_mplock in the ISRs.

78cff7365d clock.c: 
- removed TEST_ALTTIMER.
 - removed APIC_PIN0_TIMER.
 - removed TIMER_ALL.

apic_vector.s:
 - new algorithm where a CPU uses try_mplock instead of get_mplock:
	if successful continue as before.
	if fail set ipending bit, mask INT (to avoid recursion), cleanup & iret.

   This allows the CPU to return to successful work, while the ISR will be run
   by the CPU holding the lock as part of the doreti dance.

 - s_lock()
 - s_lock_try()

68126f0545 Fixed possible deadlock from recursive INTs on same cpu. Since 
we use lazy masking INTREN()/INTRDIS() might be called with INTs enabled.
This means another higher prio INT to the same cpu could attempt to
re-enter the critical region, but would spin waiting for the lock.  Since
it is the owner, it would deadlock.

31c730f3a6 New simple_lock code in asm: 
- s_lock_init()
 - s_lock()
 - s_lock_try()
 - s_unlock()

Created lock for IO APIC and apic_imen  (SMP version of imen)
 - imen_lock

Code to use imen_lock for access from apic_ipl.s and apic_vector.s.
Moved this code *outside* of mp_lock.

It seems to work!!!

480e1d62b7 Well, consensus seems very split on this so I talked it over with DG 
and he says he's happy to see forward movement in aligning our defaults
with a 16 bit world, the 8 bit folk already being veterans by this
point who know how to use userconfig.

In any case, perhaps Warner will soon come to save us all with his Dynamic
Probing(tm) feature and this will all become totally moot in any case,
so it's probably not worth arguing about either way.

f5c982d3e0 Quick and dirty (?) fix for noatime option. The WebNFS changes 
broke it by using the same value for MNT_EXPUBLIC as for MNT_NOATIME.
Just use a different value for MNT_EXPUBLIC.
